Sei Labs has acquired Bilinear Labs, a data analytics and blockchain indexing platform, in a transaction announced in September 2026. Financial terms were not disclosed.

Under the agreement, Bilinear Labs’ team will join Sei Labs and contribute to development across the Sei Network, Sei Giga, and other projects. The deal brings Bilinear’s engineering expertise and experience in blockchain data indexing directly into Sei’s development organization as Sei works to expand the capabilities and scale of its blockchain ecosystem.

Bilinear Labs is scheduled to cease operations on September 14, ending its run as an independent platform. The company built its infrastructure in Rust and developed a system capable of indexing hundreds of billions of blockchain events. It also developed BYOABI technology, adding to the technical assets that will become part of Sei Labs’ broader infrastructure efforts.

Indexing Technology Moves In-House

Blockchain indexing helps decentralized-application developers and users organize and retrieve blockchain activity more efficiently than relying solely on raw network data. In practice, indexing provides structured data that applications, analytics tools, and other services can query when tracking transactions, accounts, and smart-contract activity. With the acquisition, Bilinear’s technology and engineering talent will move from supporting a standalone data platform to contributing directly to Sei’s infrastructure and development priorities.

The transaction follows a traditional acqui-hire structure, in which a company is acquired primarily for its engineering team, technical expertise, and intellectual property rather than for the continued operation of its existing standalone business. For Sei Labs, bringing the Bilinear team into the organization could shorten the time needed to develop and improve infrastructure for a growing blockchain network. Instead of building comparable capabilities from the beginning, Sei can incorporate engineers who have already worked on large-scale blockchain data systems.

Blockchain Infrastructure Race Intensifies

The deal comes as blockchain networks compete increasingly on infrastructure, scalability, and developer tools. As networks process larger transaction volumes and applications generate more on-chain activity, efficient indexing and data access have become more important for decentralized applications, analytics platforms, and other blockchain services.

Bilinear’s experience processing hundreds of billions of events gives Sei access to a team experienced with large-scale data infrastructure. Integrating that expertise could help Sei improve how developers access and use blockchain data while supporting the network’s broader efforts toward higher performance and scalability.

The acquisition also demonstrates how blockchain companies are using transactions to address specialized engineering requirements. Data indexing, analytics, interoperability, and infrastructure engineering often require highly technical teams, making established specialists potential targets for larger blockchain developers.

Sei Labs’ decision to absorb Bilinear rather than maintain the platform as a separate operation indicates that the primary objective is to strengthen Sei’s own technology stack. When Bilinear closes on September 14, its resources and personnel will be redirected toward projects within the Sei ecosystem.

The transaction marks a shift from an independent data infrastructure business toward direct blockchain network development. By bringing Bilinear’s engineers and indexing technology in-house, Sei Labs is making the acquired expertise part of its longer-term infrastructure strategy rather than continuing it as a separate commercial product.

The acquisition was reported by CoinTrust.
